SHAFT COUPLING.

Application filed March 3, 1926. Serial No.'91,993.

This invention relates to new .and useful improvements in shaft couplings. The object of the invention being the provision of a. coupling which is flexlble to allow for variations in the axis alinements of the shafts, which is noiseless in operation and has a resilient member to absorb sudden shocks and prevent wear and tear of the parts.

Further objects of the invention are to provide a coupling containing but few parts and which is easy to install and disconnect and is inexpensive to manufacture.

Witlr" this and other objects in view my invention consists of certain novel features in the arrangement of arts, hereinaftenmore fully described and i lustrated in the accompanying drawings, in which Fi re 1 is a side elevational view of the coup ing.

- Figure 2 is a transverse vertical cross section taken on line 2-2 of Figure 1.

Figure 3 is a longitudinal cross section taken on lines 3-3 of Figure 2.

Figure 4 is an end elevational view of the resilient member.

Referring by numerals to the accompanying drawings, 10 and 11 indicate two shafts arranged in axial alinement. One of said shaftshas secured thereto a disk 12 having an outwardly projecting hub 13 in which is threaded a. set screw 14 by means of which said disk is secured in position on the shaft. A disk member 15 substantially of the same diameter as disk member 12 is arranged on the other shaft in spaced relation with said disk 12. This member 15 is provided with an outwardly projecting hub 16 in which is seated a set screw 17 by means of which said disk member 15 is secured in position on shaft 11. Disk mem-- apertures 22 formed in resilient disk 19. A series of projections or pins 23 is seated in disk 15 and project laterally and iiiwardly from said disk member into an engagement with apertures 24, also formed in resilient disk 19 in spaced relation with apertures 22. In this manner pins 21 and 23 project in opposite directions from the opposed faces of disk members 12 and 15 and alternately engage disk 19 thereby establishing driving connection between the two shafts through the medium of said resilient member 19.

Disk member 12, is provided with an annular inwardly projecting flange 12* which is spaced slightly from disk member 15 and encloses the disk 19 thereby protecting it and pins 21 and 23 from injury.

Disk 19 provides a certain amount of resiliency which. permits shafts 10 and 11 and the parts formed thereby to occupy positions out of alinement with each other without affecting the operative interengagement of said shafts. Furthermore disk 19 being resilient, any sudden shocks or excessive strains are cushioned by said member 19 thereby preventing such stresses from being transmitted from one shaft to the other.

I have shown and described the preferred form of my invention and it is obvious that minor changes in the size and construction of the various parts can be made and substituted for those herein shown without departing from the spirit of my invention.

I claim:

1. A shaft coupling comprising in combination a pair of spaced-coaxially aligned disk members adapted to be secured to the ends of two shafts, one of said disk members being provided with an inwardly rojecting hub, and the other disk member aving an annular laterally projecting flange, a disk of resilient material interposed between said disk members and arranged wholly within the space formed by said flanged disk with the ed e of said flange flush with the outer face 0 said resilient member, said resilient disk being provided with acentral opening for receiving said inwardly projecting hub, and a series ofins projecting laterally from the opposed aces of said disk members and en a silient t lis thereby forming driving interengagement between said disk members.

2. A shaft coupling comprising in com- (ill ing apertures formed in said rebination a pair of spaced coaxiallyaligned disk members adapted to be secured to spaced shafts, one of said disk members being provided with an inwardly projecting hub, a disk of resilient material interposed between said disk members and provided with a central opening forreceiving said inwardly projecting hub, one of said disk members being provided with an annular 10 flange for wholly enclosing said resilient.

disk, whereby the latter is disposed flush with the edge of said flange, and a series of pins projecting laterally and alternately rom opposed faces of said disk members and seated in apertures formed in said resilient disk, thereby forming resilient driving connection between said disk members.

Intestimony whereof I hereunto aflix my signature this 26 day of February, 1926.

JOHN O. CARREY.
